Republican Sen. Rand Paul, before a raucous crowd on Monday, demanded members of the media print the identity of the anonymous whistleblower at the heart of the House impeachment inquiry into President Donald Trump’s dealings with Ukraine.

“I say to tonight to the media: do your job and print his name,” Paul, a Kentucky Republican, yelled during a rally Trump held in support of Republican Gov. Matt Bevin ahead of Tuesday’s gubernatorial election. The crowd of Trump supporters, many donning “READ THE TRANSCRIPT” shirts, erupted into applause and cheers, and some chanted “Do your job!” and pointed toward the area where members of the press gathered to cover the event.
